Puppies left alone for too long or with too little to do or too little exercise can become over-excited during any interaction. This can cause them to play-bite intensively whenever they come into contact with someone.

While it is understandable that a puppy with too little to do makes the most of oppertunities when someone appears, the excessive play-biting can have the effect of making owners less willing to interact, causing the problem to become worse.

The solution lies in finding more for the puppy to do, with more oppertunities for off-lead free running exercise, games, and training throughout the day so that energy it used up and the puppy becomes more calm and content.
